CONNECTING AN EARPHONE/
HEADPHONES
For private listening, you can plug an earphone or mono
headphones (such as Cat. No. 33-175 or 20-210) into the
jack on top of your scanner. This automatically dis-
connects the internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you
use an earphone or headphones:
Do not listen at extremely high volume levels.
Extended high-volume listening can lead to perma-
nent hearing loss.
Set the volume to the lowest setting before you begin
listening. After you begin listening, adjust the volume
to a comfortable level.
Once you set the volume, do not increase it. Over
time, your ears adapt to the volume level, so a vol-
ume level that does not cause discomfort might still
damage your hearing.
Traffic Safety
Do not wear an earphone or headphones while you drive
a vehicle or ride a bicycle. This can create a traffic hazard
and can be illegal in some areas.
